| *Simplest way*: dump all S3 keys locally and upload them to the S3 bucket. | ||

| ### Filter the listkeys to return only the SPROXY main_chunk + sproxyd single keys | ||
|
|
||
| This step is the longest. For each sproxyd key listed in ``<RING_NAME>/s3-bucketd/``, spark workers | ||
| send a ``HEAD`` request to their local srebuildd. Each spark worker scans 2,7M keys a day with spark.executor.cores=3 |
